SPC MESOSCALE DISCUSSION 1873 FOR CNTRL/ERN GA AND SRN SC
CONCERNING...SEVERE THUNDERSTORM POTENTIAL...

VALID 241952Z - 242200Z

PULSE-TYPE THUNDERSTORMS SHOULD CONTINUE TO DEVELOP SWD THROUGH
CNTRL/ERN GA AND SRN SC DURING THE LATE AFTERNOON.  WW IS NOT
ANTICIPATED...DUE TO THE ISOLATED AND BRIEF NATURE OF THE SEVERE
THREAT.

REGIONAL RADARS HAVE SHOWN THUNDERSTORMS INCREASING IN INTENSITY/
AREAL COVERAGE DURING THE LAST HOUR OVER ECNTRL GA/CNTRL SC AND
SERN NC ALONG A LOW-LEVEL CONVERGENCE BOUNDARY.  AIRMASS S OF THIS
BOUNDARY IS MODERATELY UNSTABLE WITH 100 MB MLCAPE VALUES UP TO
1500 J/KG.  VAD WINDS SHOW NEARLY UNIDIRECTIONAL NNWLY WINDS OVER
THE SERN U.S. WITH WEAK DEEP LAYER SHEAR...NOT SUPPORTING ORGANIZED
SEVERE.  HOWEVER...35 KT NNWLY MID-LEVEL FLOW COMBINED WITH
SUFFICIENT INSTABILITY OVER CNTRL/ERN GA AND SRN SC MAY SUPPORT
ISOLATED SEVERE STORMS...WITH BRIEF DAMAGING WINDS POSSIBLE.
